Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy. This is because potential energy is directly proportional to height.

Front

What is the relationship between potential and kinetic energy during a fall?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What happens to energy when a roller coaster goes down a hill?

Back

The roller coaster converts potential energy at the top of the hill into kinetic energy as it descends.

Front

What is an example of an object with both potential and kinetic energy?

Back

A swinging pendulum has potential energy at its highest point and kinetic energy at its lowest point.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)².

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mass (m) * gravity (g) * height (h).

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, influenced by gravity.
